For this model \(\alpha >0\)  from the Dolgov and Kawasaki stability point of view [1]}.
We consider the following spherically symmetric and static line element for describing
the geometry of spacetime
\(ds^{2}=-h(r)dt^{2}+\dfrac{dr^{2}}{h(r)}+r^2\left(d\theta ^{2}+\sin ^{2}(\theta )d\phi ^{2}\right)~.\)
